Proposed drilling near suburban Denver Superfund site raising flags • Colorado Newsline

A proposed 166-well oil and gas project in suburban Denver could imperil a decades-long, multimillion-dollar effort to prevent carcinogenic chemicals stored on one of the nation’s most contaminated industrial sites from leaking into groundwater, letters from federal and state officials show.

Regulators expressed concern in May that drilling underneath and near the Lowry Landfill Superfund Site could cause small cracks in bedrock cradling millions of gallons of toxic waste in 78 unlined trenches. These fissures could allow contaminants to enter an aquifer system that millions of Coloradans rely on, wrote the U.S. Environmental Protection Agency to Civitas, the operator requesting permission to drill. The EPA oversees a complex 40-year effort to protect the health of millions of people living around the site.

The agency’s concerns stem from the issues that have long surrounded hydraulic fracturing, or fracking, a drilling process that has led Colorado in the last decade to become the nation’s fourth largest oil-producing state. The method involves pumping sand and millions of gallons of water and chemicals roughly a mile under the surface to crack shale, and release oil and gas.

“The EPA is concerned that hydraulic fracturing surrounding and underneath the site could lead to a significant unintended release of hazardous substances,” the agency wrote in May to Dan Harrington, who leads Civitas’ development initiatives. This “contamination is held in place by a bedrock layer which could, under certain conditions, be subject to microfractures from fracking.”

In response, Civitas sent a letter to the EPA in September and committed not to drill under the site, saying: “This precaution is not due to any risk associated with oil and natural gas development, but a desire to protect the Superfund remedy that is in place and operating effectively.”

The EPA cited the company’s commitment when asked if it is still apprehensive about Civitas’ plans to drill near the site and said in an email that it will “continue to coordinate with all parties to evaluate these and other site concerns.” Civitas did not return repeated requests for comment.

Natural gas production likely cause of southern Colorado earthquakes, experts say

The operator’s agreement not to drill under the Superfund site failed to reduce the anxiety of scores of households near the 50-square-mile proposed oil and gas project, which includes wells near the Aurora Reservoir. The facility is part of a system of reservoirs that store drinking water for about 390,000 people and is a popular recreation area.

Drilling currently exists about five miles from the Superfund site. Civitas is proposing well pads much closer — within about two miles. But horizontal pipes that extend beneath the proposed production area could come even closer to the site boundary.

The potential for Civitas’ Lowry Ranch oil and gas plan to disturb sensitive Superfund containment efforts brought to the fore long-running uncertainty among technical experts about whether nearby industrial operations, such as fracking, could trigger seismic activity. The U.S. Geological Survey and state agencies mapped faults near the site, as well as near the Aurora Reservoir’s dam.

Questions remain about the presence, and possible growth, of a fault at the northern end of the Superfund site and whether it’s in part responsible for allowing chemicals to leak and create a three-mile-long underground plume. The EPA says this plume doesn’t present a risk to groundwater or surface water.

Scientists have attributed earthquakes in Colorado, Oklahoma and Texas, to a surge in oil and gas operations over the last decade. These temblors were caused by injection wells, which companies drill deep into the earth and use to dispose of millions of gallons of wastewater that flows back up from fracking operations, studies found.

Hydraulic fracturing features a brief application of pressure to rock formations to release oil and gas, while wastewater injection is “an ongoing process that injects significant volumes of wastewater over long periods of time,” said Jill Carlson, an engineering geologist at the Colorado Geological Survey.

“While weak seismic events associated with fracking can be detected by seismometers, I am not aware of any surface shaking, movement or surface/near surface damage caused by fracking,” added Carlson, who is the survey’s deputy director and land-use program manager.

Uncertainty About Oil and Gas Drilling Effects on Public Health 

The Lowry Ranch oil and gas project is proposed on land owned by the Colorado State Land Board on the fringes of Aurora, the state’s third largest city. Much is at stake: Energy companies are planning massive projects ever closer to Denver suburbs, where the industrial activity exposes hundreds of thousands of residents to air pollution, spills, truck traffic and other hazards.

Proposed drilling near a Superfund site also raises new health and safety concerns residents say aren’t adequately addressed in state or local regulations. Increasingly, residents are demanding stricter rules about where fracking can take place and detailed studies that provide benchmarks for how much activity should be allowed.

“The county must insist on studies to understand the potential risks associated with fracking-induced seismicity on both the Lowry Landfill Superfund Site — and the Aurora Reservoir Dam,” wrote Kevin Lynch, an associate professor of law at the University of Denver Environmental Law Clinic, in an October letter to Arapahoe County commissioners on behalf of residents and conservation groups.

Civitas’ refiled its drilling plan on Feb. 23 after making a series of revisions requested by state regulators.  A 60-day public comment period ends April 23, and a hearing on the proposal is scheduled in front of the Energy & Carbon Management Commission for June 26.

The company’s original proposal, filed in 2022, prompted the Arapahoe County Board of County Commissioners to overhaul its  oil and gas rules. The five-member body voted 3 to 2 in November to increase setbacks between wells and reservoirs and occupied structures to 3,000 feet, and to require operators to file water quality plans and to do routine on-site air quality and noise testing.

Seismicity is a critical issue … No one is dealing with it.

The county’s new rules are allowed under a 2019 law that requires the state’s oil and gas regulator to prioritize public health and the environment over fostering energy development.

County officials said they plan to study seismicity and other issues this year when staff and commissioners start reviewing a second round of rules aimed at limiting fracking’s impacts on neighborhoods.

This rulemaking will include a proposal to ban wastewater injection wells, “which have been linked to induced seismicity in Colorado,” wrote Anders Nelson, a county spokesperson, in an email.

“We will consider other seismicity concerns as we develop the regulations,” he added, “and seek advice on that topic from the Colorado Geological Survey, EPA and the Colorado Energy and Carbon Management Commission.”

The state land board, which has owned the 26,000 acre Lowry Ranch adjacent to the Lowry Landfill Superfund Site since the 1960s, does not have regulatory or permitting authority over Civitas’ project, wrote Kristin Kemp, the land board’s outreach and communications officer, in an email.

The land board’s assets include 4 million acres of subsurface minerals. Mineral extraction leases accounted for 80% of the $2 billion the agency earned in the last decade and provided as grants to fund capital construction at schools, she said.

“Currently, more than a dozen different operators ranging from agriculture, renewable energy, recreation and mineral extraction hold leases at Lowry Ranch,” Kemp said. A company purchased by Civitas “has held an oil and gas lease on the majority of the Lowry Ranch since 2020.”

On a November conference call, Civitas executives said they are pleased with the firm’s ability to drill farther, faster and with greater production in the Denver Julesburg Basin, the state’s largest oil play along the eastern slope of the Rocky Mountains.

“We’re very excited with how 2024 is shaping up,” said Chief Executive Officer Chris Nolan of the company’s plans to expand drilling operations in the region.

A 40 Year Containment Effort Continues in Perpetuity

As controversy over the safety of new industrial activity near the Lowry Landfill Superfund Site continues, myriad local, state and federal agencies, and companies, responsible for keeping chemicals contained on the site and out of residents’ groundwater and air, never stop working. A five-year review published in 2022 found that the site remedies are “currently protective of human health and the environment.”

The city and county of Denver, which owns the 507-acre site, works with the operator Waste Management to contain pollution. Efforts to reduce and monitor contamination in soils, groundwater and surface water are overseen by the EPA and the Colorado Department of Public Health and Environment.

Containing the more than 138 million gallons of sewage, pesticides, industrial solvents and dozens of other hazardous substances dumped there requires an annual multimillion dollar coordinated effort. It also involves expensive infrastructure, such as a plant that removes methane emitted on the site and 500 regularly monitored water wells installed in the region’s aquifers.

Multiple barriers were built to hold pollution on the site including a slurry wall, a landfill cover, a groundwater extraction trench and a subsurface clay barrier. The EPA isn’t the only agency concerned about how Civitas’ oil and gas drilling proposal might impact the site. The state’s health department and the region’s Democratic congressman, Jason Crow, also expressed concern — both alerted to the issue by homeowners.

“Seismicity is a critical issue,” said Marsha Kamin, a homeowner who was unaware that wells contained in the Lowry Ranch project could be drilled within a mile of her subdivision when she moved in a year ago. “No one is dealing with it.”

On a brisk, gray January afternoon, Kamin joined other residents in a clubhouse with a panoramic view of the ice-choked Aurora Reservoir. They represented the leadership team for Save the Aurora Reservoir, or STAR — created about 18 months ago after Civitas announced its Lowry Ranch drilling proposal. The group recently retained a geologist and an environmental attorney to help them push for stricter rules.

STAR, with more than 1,000 members signed up to receive action alerts on its Facebook page, asked Crow to write a letter to the EPA in October asking what the agency plans to do about the risks posed by oil and gas operations close to the Superfund site.

The agency responded in November that it obtained an agreement from the U.S. Bureau of Land Management not to lease its minerals under the Superfund site, in addition to the acknowledgment from Civitas that it won’t drill below the site. When asked by Capital & Main about the agency’s response, Crow’s office said it will follow the drilling plan as it goes through the state and county approval processes.

“The EPA will need to monitor the Lowry Landfill Superfund Site for decades to come, and thoroughly monitor the impact of this and any proposed projects close to the site,” Crow said in an email response to an interview request. “There should be no question about the safety of Coloradans’ water.”

Colorado to weigh daily hunting limits, ban on fur sales for wildlife hunted for fur

Colorado to weigh daily hunting limits, ban on fur sales for wildlife hunted for fur 


At its upcoming meetings on July 20 and 21, the Colorado Parks and Wildlife Commission will consider whether to impose daily hunting limits for furbearers and a ban on commercial fur sales. It’s the latest chapter in a years-long debate over how these species — which include beavers, foxes, coyotes, bobcats, martens and other mesocarnivores — should be managed.  

Both potential policy changes have emerged from a surge of public interest in furbearers following Proposition 127 — a failed ballot measure in 2024 that sought to ban the hunting of mountain lions, bobcats and lynx. 

The idea to impose a limit on the number of furbearers a recreational hunter can kill in a single day has been raised in public comments and was among several recommendations made to the agency in a 2025 stakeholder group. 



While Parks and Wildlife proposed a daily limit of 15 for all 17 furbearer species in March, wildlife advocates and some commissioners pushed back, arguing it didn’t go far enough and asked staff to consider a lower number. On July 20, the commission will discuss one new option proposed by the wildlife agency — though its recommendation remains a daily limit of 15.

The idea to ban the commercial sale of furs in Colorado emerged out of a petition submitted by the Center for Biological Diversity in June 2025. 



The petition argued that it is a common-sense and ethical change that aligns furbearers with how the state manages other wildlife. In a controversial March vote, the commission approved the petition against the recommendation of Parks and Wildlife staff, sending it forward for additional debate. The first hearing will be held on July 21, with Parks and Wildlife offering two options for potential fur sales bans. The agency’s recommendation remains not to impose any ban.

A public divided on Colorado’s current furbearer management 

Public sentiment around furbearers is largely divided into two groups. 

The first, primarily represented by sportspersons and agriculture advocates, argues that the agency’s current management is driven by science and represents a critical part of Colorado’s hunting heritage that provides critical data to the agency. The second, held by wildlife conservation and welfare advocates, contends that the management of furbearers is outdated, unethical and leading to overexploitation of the species

Currently in Colorado, all 17 furbearer species can be hunted with the purchase of ​​a $10 permit. In its 2024-25 fiscal year, the agency sold 19,620 furbearer permits. There are no limits on the number that a permit-holder can kill.

These species are grouped together as mesocarnivores, sharing high reproductive output, high natural mortality rates and qualities as habitat generalists, according to a March report. 

In a July memo to the commission, Parks and Wildlife Director Laura Clellan wrote that “current annual harvest rates range from 0.6-5.8% of the conservative population projections,” and that there is no scientific evidence that the current level of furbearer hunting is causing population declines.

Parks and Wildlife staff have said that the allowed methods of trapping — which were narrowed significantly by a 1996 ballot measure in Colorado — act as a natural limit on how many furbearers can be hunted.

There have been some concerns and criticism that Parks and Wildlife lacks sufficient population estimates for these species. In the memo, Clellan clarifies that the wildlife profession tends not to use population abundance for small game and furbearer management because their populations are limited, not by harvest, but by factors like weather and habitat — meaning there are “often very large population swings year to year.”  

While Colorado law makes it illegal to sell or purchase wildlife for commercial gain, there’s an exemption that allows the sale of “nonedible portions of wildlife,” including furbearer pelts and hides. This includes allowing the sale, barter or trading of items like fur, feathers, teeth, horns, antlers, bones and more that were acquired legally.

When it comes to imposing a daily limit on the number of furbearers a hunter can legally kill, the agency has offered two options. The first is a limit of 15 that applies to all furbearer species hunted for sport in Colorado. According to Clellan, this is still the agency’s recommendation. 

The second would apply a limit of eight or four, depending on the species. The higher limit of eight would be applied to species identified by state law as those that can cause property damage: badger, bobcat, beaver, coyote, muskrat, striped skunk, western spotted skunk, raccoon and red fox. The lower limit of four would be applied to mink, opossum, marten, ring-tailed cat, gray fox, swift fox, long-tailed weasel and short-tailed weasel.

In her memo, Clellan said the reason Parks and Wildlife is considering a limit is in response to perceptions that there is a “regulatory loophole allowing unlimited, unsustainable harvest and a regulatory gap between how furbearers are managed in comparison to small game.”

She added that it would also help maintain “social acceptance” of recreational hunting of furbearers.

“There is no information that suggests reducing harvest is necessary to sustain adequate furbearer populations throughout their respective ranges in Colorado,” Clellan wrote, adding that daily limits would only “affect a small number of hunters or trappers, as the vast majority of Colorado furharvesters take only a few animals, even across the whole harvest season.”

Should Colorado ban the commercial sale of furs from furbearers? 

In a July issue paper identifying potential options for a ban on the sale of fur, the agency gives three potential options for the commission to consider. Parks and Wildlife indicates that the alternatives offered are “substantially different” from the petition to avoid potential regulatory conflicts.

The first — recommended by Parks and Wildlife staff — is not to implement a ban, citing its previous denial of the petition. Clellan wrote in the denial recommendation that there was no “solid evidence that commercial fur sales drive harvest levels in Colorado.” 

The second option would prohibit the sale of “fur products,” defined as the pelt, hide or any part of a furbearer hunted in Colorado. The third would ban the sale of “raw pelts,” referring to the skin or any part of the furbearer intact with skin that has not been tanned. Both would only apply to fur sales within the state, meaning an animal legally hunted in Colorado could still be sold in another state.

The agency reports that both of these would have enforcement challenges. 

Both the second and third would exempt any furbearers killed for tribal uses or by private landowners and producers dealing with nuisance animals. The latter is currently legal under a state law that allows these individuals to kill nine of the furbearer species for causing damage to crops, private property or livestock without a license. 

In between the March and July meetings, Parks and Wildlife solicited feedback on a potential ban on its EngageCPW.org website and through several stakeholder groups.

The survey received 726 responses, with 57% opposing a commercial fur sales ban. Opponents said the proposal lacks scientific justification, goes against Parks and Wildlife staff recommendations, could hurt local economies and businesses, and would remove an important wildlife management tool.

About 38% supported the ban, citing animal welfare, ethics and the ecological importance of furbearers. Many said ending commercial fur sales would stop the commercialization of native wildlife, arguing that trapping and fur harvesting are inhumane and that the animals should be managed for their ecological value rather than commercial use.

The commission’s March decision to go against staff’s recommended denial of the petition has raised concerns about the overall direction of the board and agency.

“The consequence will be that now there is an onslaught of petitions coming your way that will tie up your CPW staff,” said Rio Blanco County commissioner Callie Scritchfield at the commission’s May meeting. “Colorado is moving more and more toward ballot-box biology, and now petition biology. This allows for management based on emotions and politics, and I haven’t seen any evidence that that’s more successful than managing based on our science and experience on the ground.” 

Others, however, supported the commissioner’s decision to allow the petition a hearing. In May, Delia Malone, an ecologist based in Redstone, said the “vote to support an ethical, science-based relationship with our natural world by voting to protect native furbearers from commercialization has been one of the most important votes in Colorado in the last century.”

“The commission has made great progress in moving Colorado towards the ethical ecological light of the moral universe and out of the scientifically unethical world where guns dominate wildlife management, and killing is misconstrued as conservation,” she said.

Colorado reports 90 cases of Cyclospora this year: Here’s what health officials want you to know

Colorado reports 90 cases of Cyclospora this year: Here’s what health officials want you to know


As health officials investigate a growing multistate Cyclospora outbreak, Colorado public health leaders say there is no evidence of an increased risk from produce sold in Colorado.

The Colorado Department of Public Health and Environment (CDPHE) has recorded about 90 Cyclospora cases so far this year, according to State Epidemiologist Dr. Rachel Herlihy.

Centers for Disease Control


“We typically annually see about 167 cases of this infection in the state,” Herlihy said. “We do typically see more infections due to Cyclospora in the spring and summertime.”

Cyclospora is a parasite that causes an intestinal infection known as cyclosporiasis. Symptoms typically begin about a week after exposure and commonly include watery diarrhea, stomach cramps and nausea.

“It is not pleasant, that’s for sure,” Herlihy said. “But we don’t see high hospitalization rates associated with this particular infection.”

The parasite is most often spread through contaminated food or water. Produce such as leafy greens, herbs and berries has been linked to previous outbreaks.

“This particular parasite can be difficult to wash off of produce,” Herlihy said. “It can stay attached to greens or herbs or berries, even after you wash them.”

The warning comes as federal investigators work to identify the source of a growing outbreak affecting several Midwestern states. While the CDC’s public dashboard currently lists only 1 to 10 Colorado cases, Herlihy said those numbers are outdated because they only include reports through the middle of June.

“The outbreak that is occurring outside of Colorado really appears to have started to increase significantly in late June,” she said. “We certainly expect the CDC numbers to go up because the state health department numbers that are not yet reported on the CDC website are much higher.”

Reba Pousma, who lives in the Denver area, has been suffering from symptoms like the parasite for a week. A doctor she spoke with believes Cyclospora could be the cause of her illness, though her source of exposure has not been confirmed.

“It’s definitely different from regular food poisoning,” Pousma said. “I wouldn’t wish this on my worst enemy.”

She believes her symptoms started after eating a salad last week. She’s still battling stomach cramps, exhaustion and relentless trips to the bathroom.

“I’m on day five now of going to the bathroom over 40 times a day, and nothing has been solid,” she said.

She posted about her experience online, and the video has drawn thousands of comments, many from people who say they’re experiencing similar symptoms.

“There’s a lot of people commenting that they’re experiencing the same symptoms,” Pousma said. “I think some people are worried, and some people are like, ‘Oh my gosh, this is me too. Thankfully, somebody’s talking about it.’”

Unlike the Midwest outbreak, Herlihy said most Colorado cases reported so far this year have been linked to international travel, not food purchased or consumed in Colorado.

When someone tests positive, CDPHE investigators conduct detailed interviews about where they traveled, what they ate, restaurants they visited and grocery stores where they shopped to help identify possible sources of exposure.

Testing for Cyclospora requires a stool sample, typically using a PCR test that detects the parasite’s DNA.

Most people recover without treatment, but Herlihy said symptoms can linger for weeks and may come and go. Antibiotics can shorten the illness, particularly for people at higher risk, including young children, older adults and those with weakened immune systems.

For now, CDPHE says Coloradans don’t need to avoid fresh produce but should continue to follow safe food-handling practices by washing produce under cold water, washing their hands before and after handling food, scrubbing firm fruits and vegetables when possible, and refrigerating cut or cooked produce promptly.

“There is no reason to believe that there’s any increased risk of exposure to Cyclospora from eating produce in Colorado,” Herlihy said. “But it is always a good idea to thoroughly wash produce.”

Body found in western Colorado believed to have been eaten by bear


An investigation is underway after authorities found a body near a picnic area in western Colorado last weekend that appears to have been eaten by a bear.

The Mesa County Sheriff’s Office says the human remains were located on Sunday near the Wild Rose Picnic Area off Lands End Road on the Grand Mesa. Investigators say the remains were scavenged and scattered, and they believe the person was consumed by a bear and other wildlife.

The Mesa County Coroner’s Office is working to identify the person and officially determine their cause of death.

The sheriff’s office is asking anyone who was in the area of the Wild Rose Campground between June 22 and July 5, 2026, and noticed anything suspicious to contact Investigator Jenna Reed at (970) 244-3274.

They added that Colorado Parks and Wildlife believes there is no threat to the community at this time.

The area is home to black bears, and the MCSO shared several guidelines for the community to prevent human-bear conflicts:

  • Stay alert and together: Go with others when possible, keep children in sight and close by, and avoid using headphones so you can hear your surroundings.
  • Food safety: Double-bag food, pack out all food and trash, and don’t burn scraps and trash in fire rings/grills or leave them behind.
  • Pet safety: Keep dogs on a leash at all times or leave them at home; don’t force a bear to defend itself.
  • Camping safety: Set up camps away from dense cover or natural food sources and do not cook or store food near/in a tent. Secure food in bear-resistant containers or suspend at least 10 feet above the ground and 10 feet away from any part of the tree.
  • Know how to respond: Don’t approach bears; quietly move away. Never run, as it may trigger a chase response. If a bear approaches, stand your ground, wave your arms, and yell until it leaves. Stay with your group, use bear spray, and fight back aggressively if necessary.
  • Bear spray: Carry bear spray and know how to use it correctly. It’s not repellent; don’t spray your tent, campsite, or belongings.
